IC-M23 Float’n flash* VHF Radio.
With its innovative flashing red LED light, an overboard IC-M23 is easy to find, day or night.
The light flashes even if the radio is turned off. * US patent pending.
Smallest and lightest in the world. As a buoyant VHF marine transceiver, the
IC-M23 has the smallest and lightest body in the world.* * As of February, 2011, researched by Icom.
Energy-saving 3.7V circuitry* The IC-M23 is powered by the 3.7V Lithium-Ion
battery pack, BP-266, to reduce the capacity and weight of the radio. A newly developed PA
circuit provides 5W (approx.) RF output and powerful 600mW (typ.) audio even at this low
voltage, while saving battery consumption for 10 hours of operating time.*
* Typical operation with Tx (Hi): Rx: standby=5:5:90.
The large, easy to see LCD (32×16 mm) offers a clear 2 - digital channel number indication.
Built-in regulated charger circuitry Recharge the IC-M23 by plugging the wall charger directly in to the radio.
By eliminating exposed metal charging points, the IC-M23 is even more protected from water damage.
The volume loud/mute functions temporarily change the volume to the maximum/minimum
level with two touches of a button. Depending on the background noise level, you can
easily change the volume level to capture the received message.
